我一直在尝试使用 sqlalchemy 将数据转储到 mysql 数据库中。当我尝试这样做时，它给出错误 sqlalchemy.exc.ArgumentError：列表参数必须仅包含元组或字典 。以下代码用于插入。
def insert_data(db, table, rows):
db.execute(f"INSERT INTO {table} VALUES (%s)", rows)
db.commit()
rows中的内容如下。
[(1, 'asdsewadada', 'lajsdljasld', 'lol@gmail.com', 51)]
所以，我插入的是元组列表，但仍然遇到相同的错误。
从 SQLAlchemy 版本 2 开始，您应该使用字典而不是元组：
所以这应该修复你的代码：
def insert_data(db: sqlalchemy.engine.base.Engine, query: str, parameters: dict): log_headline: str = "insert_data() ::" """ :param db: :param query: INSERT INTO votes (time_cast, candidate) VALUES (:time_cast, :candidate) :param parameters: {"time_cast": time_cast, "candidate": team} :return: """ # Insert stmt = sqlalchemy.text(query) try: # Using a with statement ensures that the connection is always released # back into the pool at the end of statement (even if an error occurs) with db.connect() as conn: conn.execute(stmt, parameters=parameters) conn.commit() print(f"{log_headline} OK inserted data ") except Exception as e: # If something goes wrong, handle the error in this section. This might # involve retrying or adjusting parameters depending on the situation. print(f"{log_headline} Error {e}")
